These questions need to be addressed to your Realtor. But to answer the question in a vague way , certainly depends on why you feel like your stuck. Did you lose your job, are you relocating, are you getting buyers remorse, has your family tryed to talk you out of buying, have you found a better home for a better price, has your contract expired, did the home not meet your expectations?
You see there are so many reasons why you feel you are stuck and we here can only guess.
Please talk with your Realtor who has experienced this same question you have asked here, your not the first one who has felt this way.
Good luck my friend.
